I’m not going to pretend to know your situation, but I also have anxiety and I can say with certainty that bottling it up won’t help. I prefer to cope by writing–journal entries, poems, whatever. But if your anxiety feels like it’s “too much already” you should always reach out to talk to someone. There are anonymous hotlines to talk to someone.
I know how hard it can be to juggle so many overwhelming things at once–for me it’s anxiety caused by OCD and ADHD. Sometimes it helps to get out of my head by reading. But everyone is different. You just need to find what helps you. And, again, don’t be afraid to talk to someone.
